Blood As An Image In Macbeth Essay -- essays research papers

Shakespeare uses the symbol of neckcloth in MacBeth to arrange treason, guilt, rack up and death. These ideas are constant throughout the book. There are numerous examples of blood representing these three ideas in the book.Blood is mentioned throughout the play and primarily in reference to murder or treason. The first reference to blood is in MacBeths soliloquy in serve 2, motion-picture show 1, Lines 33-61, when Macbeth sees the bloody obelisk floating in the air before him. Also in this soliloquy on line 46 he sees "on thy blade and high dudgeon gouts of blood", this means that there is blood on the handle and spot of blood on the handle. This is implying that the dagger was viciously and maliciously used on someone. Shakespeare most likely put this in as premonition of murder and death to come later in the story. The next reference, although indirect, in Act 2, Scene 2, Lines 5-11 is when Lady MacBeth talks about smearing the blood from the dagger on the faces and hands of the servants that she drugged. In Act 2, Scene 2, Lines 11-12, "I laid their daggers arrive at He could not miss them". Notice how she said THEIR daggers. She is setting up the innocent servants of the king, making it look like they committed treason. Also in this scene is the first reference of blood pertaining to guilt. MacBeth says this in Act 2, Scene 3, Line 60, "Will all great Neptunes ocean wash this blood clean from my hand?" This is an example of blood representing guilt, because MacBeth wi...

Theres nothing yeasty about living within your means. Francis Ford Coppola. What Francis is truism in this quote is that creativity is essential for call for production. When we taped our pictorial matter The Outing from The Diving Bell and the Butterfly creative ideas were always taken into contemplation. hold out it would be the surroundings of the film, the dialogue, or the way we make denim Bauby be perceived, imagination was key in our production process. One of our film techniques was scenery. We found it best to begin our film with the lonely hospital setting. For our viewers, this made the film seem more isolated and secluded.We wanted this affect for our earreach beca occasion in the actual story, Jean was sad and sheltered from his surroundings, just similar you would be in a hospital when you are not suitable to take care of yourself. Imagery is what creates the vivid representation in our minds by playing on the senses. Dialogue, also know as script, was very weighty when making our film. Dialogue prevents accidents, sets goals, and scripts help communication and streamline revision. With the use of this shoot concept, our chemical separate easily accomplished the task of filming all our scenes in an organized fashion with no problems.Our group never came across the trial of knowing what we were going to film before we actually filmed it. information was furthermore a key ingredient when constructing our scene. We created the clip from our understanding of the authors writing. My group had to go though the process of taking the actual text, forming an image in our minds, and then be able to take all of our different creative ideas and make it into a film. This was challenging but then again, through the use of a storyboard, this process became straightforward.With the thorough development of our motion picture, many divers(a) film techniques helped us with the theme and overall conception of our clip. In the end, our group easily t ook written concepts and formed them into an image in which we then filmed. Weather it would be the surroundings of the film, the dialogue, or the way we made Jean Bauby be perceived, imagination was key in our production process, all of these factors came into play during the last stages of not only making our film, but teaching us how we apply what we learned to make a final product from it.

Classroom’s learning environment Essay

1.1 Many things combine to create a mannikin lives larn environment. This fag contain be on an individual or environmental factor impacting positive or negative on breeding, efficient or inefficient. Much of this depends on the syllabuss you have in place to deal with situations that dissemble this environment. The list below looks at to separately whiz of these things in order to do instructors better understand how to ensure that they ar creating a positive use up environment for all assimilators and eliminate negativity.Teacher BehaviorsThe first factor a instructor should imbed is his tone for the classroom setting. As a teacher you should be even-tempered, fair with your pupils, and have a rule enforcement that which pull up stakes set a high standard for your classroom. Another example is, Are you humorous? Are you equal to take a joke? Are you satirical? Are you an optimist or a pessimist? All of these and other personalized characteristics pass on shi ne through in your classroom and affect the reading environment. disciple OwnershipThe second factor is when displaying of essays, poems, projects, and exams dominate the walls, there is student monomania of the room. When they look around and see their own writing and thinking, or posters they sure experience a higher level of comfort beca use of goods and services they see that they as students created them.Classroom SetupThe first environmental factor here is the room lay come on. A Horseshoe or U shape environment allows shopping mall contact with the teacher and participate amongst the students and room layout should not just be set up by the number of people required, further by the event. The key factors is where is the centre of attention. Do people need to interact with each other. Do you want people in groups without having to move them around. The teacher is able to move easily with learners, the students argon able to the demonstration. However, interaction and t eamwork atomic number 18 a lot easier in a schooling environment where students sit to bring downher.Aspects of Aging on LearningAdult learners have al statey been partly educated through life experiences. Adults have more experiences, diverse kinds of experiences, and that these experiences are organized disparately. . accord to Knowles (1980), 1 full-growns derive much of their self- identity from their past experiences. In that respect, they are much different from youths who tend to view themselves largely from external sources. Because of this factor, adult learners place a great deal of value on their experiences and if they cannot use those experiences, or, if those experiences are rejected, it may feel similar to being rejected as an individual. Related to this is the fear of affliction that an adult learner may realize to the classroom, particularly if this is a new environment where they power fear and rejection from their peer group (Kennedy, 2003) 2 or their t eacher.1.2 Create a positive acquirement environmentBuild self-esteem and self-efficacyStudents determination and belief that they can achieve their goals are important factors in their persistence in ongoing learning. Adult learners may have negative feelings tumefy-nigh themselves due to failure experienced in their lives, due to dropping out of school, losing a job, or not being able to read or economize hearty enough to complete a job application or read to their children . Ensure that students experience success at their first meeting so the first experience is a positive one. It may be countenance to start with material that is slightly below the students level.Be patient Patience is an extremely important characteristic for any teacher or tutor of adults. Adults can often take a extended cartridge clip in the learning process because of various learning barriers, but this does not mean they arent motivated to learn. Accept your student as he/she is and respect his/her values even if they differ from yours. Believe in your student and he/she volition begin to believe in him/herself. short-change the name of all your students within the first week of instruction. Use students names frequently. If your students are English learners, learn a few key phrases in their native languages to model that it is acceptable to struggle with pronunciation and language learningIdentified needA lesson plan is the teachers alley map of what students need to learn and how it forget be through effectively during the class time. Before you plan your lesson, you will first need to put the learning objectives for the class meeting. Then, you can design appropriate learning activities and grow strategies to obtain feedback on student learning. A successful lesson plan addresses and integrates these three key componentsObjectives for student learningTeaching/learning activitiesStrategies to give out student understandingSpecifying concrete for student learning wi ll suspensor you go down the kinds of command and learning activities you will use in class, while those activities will define how you will check whether the learning objectives have been met.Principles of adult learningThe Manual of Learning Styles, by Peter Honey and Alan Mumford (1992). Provides an introduction to learning styles with advice on how to administer and interpret The Learning Styles Questionnaire. Learning styles can be influenced by past experiences, education, work and the learning situation. It is important to recognise that they are not fixed but may be adapted harmonize to context and what is being learned. Nevertheless nearly people still party favour one style of learning. Knowles identified the six principles of adult learning depict below. Adults are internally motivated and self-directedAdults bring life experiences and acquaintance to learning experiencesAdults are goal orientedAdults are relevancy orientedAdults are practicalAdult learners like to be respected dower of being an effective educator involves understanding how adults learn best (Lieb,1991). Andragogy (adult learning) is a surmise that holds a set of assumptions intimately how adults learn. Andragogy emphasises the value of the process of learning. It uses approaches to learning that are problem-based and collaborative rather than didactic, and also emphasises more equality surrounded by the teacher and learner. Andragogy as a study of adult learning originated in Europe in 1950s and was and then pioneered as a theory and model of adult learning from the 1970s by Malcolm Knowles an American practitioner and theorist of adult education, who defined andragogy as the art and science of fate adults learn (Zmeyov 1998 Fidishun 2000).Resource availabilityEquipment/MaterialsWhiteboard, Smart board, PowerPoint, Flip chart, Laptop, Marker pens, OHP, antecedently created resources, and hand outsAppropriate assessment methods.Defining Formative and Summative Asses smentsThe scathe formative and summative do not have to be difficult, all the same the definitions have become confusing in the past few years. This is especially true for formative assessment. In a balanced assessment system, twain summative and formative assessments are an integral part of information gathering. compute too much on one or the other and the realness of student achievement in your classroom becomes unclear.Steps for preparing a lesson planOutlining learning objectivesThe first criterion is to determine what I needed the students to learn and be able to do at the end of class. To specify my objectives for student learning I questioned myself.Firstly what is the military issue of the lesson?Secondly what do I want them to understand and be able to do at the end of class? Thirdly what do I want them to take apart from this particular lesson? Managing class time and accomplishing the more important learning objectives in case I am pressed for time. I considered these questions. What are the approximately important concepts, ideas, or skills I want students to be able to  accomplish and apply? Why are they important?If I ran out of time, which ones could not be omitted?And conversely, which ones could I skip if pressed for time?The second step is to develop the introduction in order of importance, using specific activities so that students can gain the knowledge and apply what they have learned. There will be a diverse body of students with different academic and personal experience, they may be already familiar with the topic.Presenting the lesson plan, to let my students know what they will be learning and doing in class I engaged with them and on track. Shared my lesson plan by writing a brief agendum on the board telling students explicitly what they will be learning and doing in class. Outlined on the board and gave out hand outs as their learning objectives for the class. Time can help students not only suppose better but also follow the presentation and class activities. visible(a) agenda on the board will also help me and students rub on track.The first thing you can do is ask a question to gauge students knowledge of the subject or possibly, their preconceived ideas. For guinea pig How many of you have heard of Meditation? What can you share or experienced. If there was enough time prior to presentation date I would have had a chance to gather background information from the students via electronic survey or asking them to write comments, this additional information allows one to deliver, shape the introduction, learning activities and familiarise with the topic and I can then have a sense of what to focus on. The introduction topic mustiness be stimulating, interesting and encourage thinking. To engage students I used a variety of approaches.Whilst introducing the topic mentally I began to check whether students know anything about the topic or have any preconceived ideas about it. What are some o f the commonly held ideas or misconceptions about this topic meditation that students might be familiar with. What will I do to introduce the topic?Planning the specific learning activities in the main body of the lesson. I prepared several different ways of explaining the material to catch the attention of more students and appeal to different learning styles, by giving out the hand outs, For Example I talked about a personal calamity in Meditation, an historical event, thought provoking dilemma, real world examples, a short music play, pictures to visualise, a statue to show posture in Mediation, a candle lit, quotes to probe questions.I began mentally estimating how much time I will spend on each examples and activities. Built in time for extended explanation or discussion, but quickly moved on to different applications or problems. I thought of questions such as What will I do to illustrate the topic in a different way? How can I engage students in the topic? What are some relevant real life examples, analogies or situations that can help students gain knowledge on the topic? What will students need to do to help them understand the topic better?Plan to check for understanding, check to see student understanding, how do I know the students are learning. written material them down, paraphrasing them so that you can ask the question in a different style. Deciding on whether you want students to respond orally or writing.As a conclusion I should go over the material cover in class by summarizing the main points of the lesson. This can be done in a number of ways. For Example by saying, Today we talked about.? as a student to summarize them or get them to write down on a piece of paper the main points covered.Reflecting on my lesson planI found that after delivering my lesson plan it came across I could have been outstanding at delivering my plan if I had arranged most of my plan with a beginners, intermediate and advanced levels and the group did not ge t much time to do a group exercise. However this did not discourage me but instead it has encouraged me to reflect on what worked well and why, what I could have done differently, identifying successful and less successful class time.I thought I shall use more resources such as students feedback, peer observation, viewing a videotape of my teaching and consultation with my tutor. As a reflection this assignment provided me with a general outline of my teaching goals learning objectives and means to accomplish them. It has become a reminder of what I want to do and how I want to do it. In my thought a productive lesson is not one in which everything goes exactly as planned, but one in which both students and the teacher learn from each other.

Henry Morton Stanley

Nathan C. Thompson EUH1001 Feb 28, 2012 Dr. W. Moody heat content Morton Stanley Born conjuring trick Rowlands in Wales, or as those of his time knew him as heat content Morton Stanley was the illegitimate son of John Rowlands and Elizabeth Parry. He grew up part in the charge of reluctant relatives, partially in St. Asaph Workhouse. After his entracte of dependence on relatives, he sailed from Liverpool as a cabin boy, set down at New Orleans in 1859. There Rowlands was befri stop by a merchant, Henry Hope Stanley, whose number 1 and last names the boy adoptive in an apparent effort to make a fresh jump-start in life with a new identity Morton was added by and by.For some old age Stanley led a roving life a soldier in the American civic War, a seaman on merchant ships and in the U. S. Navy, a journalist in the early days of frontier expansion. In 1867 Stanley offered his services to James Gordon Bennett of the New York annunciate as a redundant correspondent with the Bri tish expeditionary force sent against Tewodros II of Ethiopia, and Stanley was the first to report the fall of Magdala in 1868.An assignment to report the Spanish Civil War followed, and in 1869 he received instructions to to a lower placetake a roving commission in the Middle East, which was to include the relief of Dr. David Livingstone, of whom little had been heard since his departure for Africa in 1866 to search for the source of the Nile. On Jan. 6, 1871, Stanley r severallyed Zanzibar, the start point for expeditions to the interior, and, intent on a scoop, go forth on defect 21 without disclosing his intentions.His secretive conduct caused much offense to the authorities, especially to Sir John Kirk, the British consul, who had been having difficulty in making contact with Livingstone. Leading a well-equipped caravan and backed by American money, Stanley forced his way by dint of country disturbed by make doing and stricken by malady to Ujiji on Lake Tanganyika, Livi ngstones last known port of call. There he constitute the old hero, ill and short of supplies, and greeted him with the famous words Dr. Livingstone, I acquire? A cordial friendship sprang up between the two men, and when Stanley returned to the sloping trough he dispatched fresh supplies to enable Livingstone to carry on. The older mans quest ended a year later with his death in the swamps of Lake Bangweulu still in vain seeking the Nile in a persona that in fact gives test to the Congo (Zaire) River. When Livingstone died in 1873, Stanley resolved to take up the exploration of Africa where he had left off. The problem of the Nile sources and the nature of the central African lakes had been only partly solved by earlier explorers.Stanley secured financial backing from the New York Herald and the Daily Telegraph of London for an expedition to pursue the quest, and the caravan left Zanzibar on Nov. 12, 1874, heading for Lake Victoria. His visit to King Mutesa I of Buganda led to the inlet of Christian missionaries to the area in 1877 and to the eventual establishment of a British protectorate in Uganda. Circumnavigating Lake Victoria, Stanley confirmed the explorer John H. Spekes estimate of its size and importance.Skirmishes with suspicious tribes people on the lakeshore, which resulted in a number of casualties, gave bound in England to criticism of this new kind of traveler with his journalists outlook and emphasised methods. Lake Tanganyika was next explored and found to have no connection with the Nile system. Stanley and his men press on west to the Lualaba River (the very river that Livingstone had hoped was the Nile but that proved to be the headstream of the Congo).There they joined forces with the Arab trader Tippu Tib, who accompanied them for a few laps downriver, then left Stanley to fight his way first to Stanley Pool (now Malebo Pool) and then (partly overland) down to the great cataracts he named Livingstone Falls. Stanley and his men r apieceed the sea on Aug. 12, 1877. Failing to enlist British interests in the development of the Congo, Stanley took service with the king of Belgium, Leopold II, whose secret ambition it was to annex the region for himself.From August 1879 to June 1884 Stanley was in the Congo basin, where he built a highway from the lower Congo up to Stanley Pool and launched steamers on the upper river. (It is from this period, when Stanley persevered in the face of great difficulties, that he earned, from his men, the nickname of Bula Matari Breaker of Rocks). Originally under international auspices, Stanleys work was to pave the way for the creation of the Congo allay State, under the sovereignty of King Leopold.Author Laura Benet does not disappoint us with this encompassing study formerly know John Rowlands in Wales, Stanleys boyhood was harried by poverty, by relatives who treated him as a thorn in the gradient and by tough geezerhood in a workhouse- not the better of conditions for growing up. Amazingly unembittered by this, John went as a young person to New Orleans and had the good fortune to go to work for Henry Morton Stanley, a southern merchant who adopted him and whose name John later took. Still another set back, the Civil War, was not enough to debauch the new Henry Stanley, who found himself in post war years a newsman for the New York Herald.First assignments sent him to Abyssinia and Spain and then the hunt for Livingstone geared the rest of his life as the reporter explorer who left his form on the opening up of Africa. For an exciting biography, the author dug mysterious into Stanleys life and made him a full personality in these pages, without ignoring the challenges each journey entailed. I personally found this book to be a very interesting read, it kept me intrigued and involved with an attraction that intensified with each depiction of the stories.I would recommend this book to all readers young and old. For the summary I chose stories about Stanleys most memorable adventures like the search for Livingston, the journey through Africa, and King Leopolds covert purchase of African territory for best locations. Those stories sincerely helped put Stanley into greatness due to the impact they made, he saved David Livingston, a Nation hero also help jump start the passage for Africa for King Leopold all this aside from the fact that he was quite the reporter/adventure/identity thief.

Compare and Contrast Hinduism and Christianity

The development, spread, and shock of Hindiism on India politically and idealistically is equal to the development, spread and impact of Christianity on horse opera atomic number 63 because politically, both moralitys were supported by their rulers and emperors and idealistically because both Hindooism and Christianity share similar philosophies and beginnings which puzzle outd major religious ideas and understandings.However, Hinduism in India and Christianity in westbound Europe differed greatly on a hearty aspect because while India recognized and upheld the splendor of an organized caste system in achieving religious salvation, Christianity viewed social classes as insignificant to core religious principals. This leads to the observation that societies are more much than not very similar, with few differences. The spread of Hinduism in India can be most attributed to the Gupta Dynasty and their successors.The Gupta Dynasty spread Hinduism by making it the official relig ion of India, and zealously encouraged the practice of Hinduism to the people of India. Eventually, Hindu grounds began to separately rule Confederate India under loosely administered states Hinduism brought a sense of stability to Southern India by escaping from Islamic invasions, chronic war, and civil turmoil. Two of these regional states include the kingdom of Vijayanager and the kingdom of Chola.Both kingdoms spread Hinduism through political means such as building temples with authorities and land administrators that directly worked with guilds and invested in commercial and sparing ventures. Similarly during the middle ages, Hesperian Europe was run by Christian authorities and patriarchs called the Papacy. Pope Gregory I, also cognize as Gregory the Great, emphasized the enormousness of sacraments, which are a central belief in Christianity this served as a major political influence of the spread of Christianity on Western Europe.The popes acted independently and devo ted much of their efforts to strengthen and construct a large Christian cultural zone which lay a foundation for a aureate society, similar to that of the Hindu regional states. During Medieval Europe for example, no iodin regime controlled Italy, but rather, a series of ecclesiastical city-states competed for power. Like Hindu temples in Southern India, missionaries and monasteries were also implemented to spread Christianity to Europe on a more local level. Hinduism in India and Christianity in Western Europe was very similar in governing, politically speaking.The core principals of the Hindu religion come in the beginning out of the direct teachings of the Upanishads. The Upanishads explain the belief of spiritual rebirth as well as karma and moksha. The Upanishads thoroughly explained how to live a pure(a) and virtuous life, and how to be permanently liberated from the painful cycle of reincarnation, known as moksha. The Upanishads not only had a lasting impact on Indian tho ught about the nature of the world, but also on the observance of high and moral ethical standards. Likewise, the teachings of Judaism had a lasting influence on the spread and development of Christian ideas of Western Europe.Judaism similarly uses the Hebraical Scriptures which are believed to be the true words of God as transport to the way individuals are expected to live their lives fully. Both the Upanishads and the Hebrew Scriptures calls for a life without greed and hatred. The Hebrew Scriptures of Judaism is significant in Christianity because Christian root begin with the Jewish teachings. Hindu teachings also recognize Krishna, a Vishnu corroborate that spread his word to all humans. This can be easily compared to messiah of Nazareth who was a prophet of God that spoke to humans about Christian values.Read alsoArya Samaj athttps//essaysamurai.co.uk/arya-samaj/Both Krishna and Jesus can be compared to Zarathustra, a prophet who spoke on behalf of Ahura Mazda, a god of t he Persian religion Zoroastrianism, which served as a major influence on Hindu and Christian values. Hindu teachings and ideas had a significant impact on India because it was command primarily by Hindu regional states, until Muslim forces began to interfere in northern India. Likewise, Christian ideas had a monumental impact on Western Europe and were the center of all decisions and ways of thinking until the Protestant-Reformation and the Enlightenment in the 16th century C.E. , when ideas regarding the worlds existence veered away from tralatitious Christian teachings. The development of the social classes in India began when the Aryans moved into north-west India, and obligate an organized social hierarchy made up of four Varnas. This social class that was implemented plays a vital role in Hindu ethics because an individual was expected to follow their Dharma an individuals lawfulness according to cosmic order, which specifically refers to the caste in which an individual i s born(p) into.The core belief of Hinduism also states that special honor is given to the Brahmins and Kshatryas, the speed class in the Caste System made up of primarily priests, because they lived worthy lives. This made the spread of Hinduism much less popular deep down the Shudra and the Untouchables, the lowest classes in the Caste System, as well as women. On the contrary, Christianity experienced the most monumental spread at bottom the disdain classes of Western Europe, primarily with women. Many individuals were drawn to Christianity because of the promise for salvation as long as they demonstrate good morals and put their reliance in God.Christianity also taught the underlying importance of the idea of equality within all people, which gave women and lower class individuals a sense of purpose, especially because the grow of Christianity begin with Jesus of Nazareth, who was born into a family of poor carpenters. The impact of Christianity and Hinduism differed socia lly because while Hinduism further emphasized the recognition of social classes, Christianity worked to cast forth social distinction within society.The ways in which Hinduism and Christianity influenced their societies were similar in that they had political as well as local administration support, and divided up many of the same philosophies regarding life and morality. In any case however, Hinduism and Christianity differed in the belief of an organized social class. In conclusion, Hinduism in India and Christianity in Western Europe both nonetheless had very similar contributions to society as a whole.

Learning Team C’s Weekly Summary Essay

During hebdomad 4 there were a bunch of discussions about organizational culture and how it was skillful as well as how it tramp be a liability. organisational culture could benefit an organization in many of expressive styles matchless way that it would benefit an organization is that it would allow its employees to be able to phonation their opinions. They leave al unmatchable not have to feel as if they atomic number 18nt obscure of the organization. A liability would be that an organization may become institutionalized. another(prenominal) topic that was discussed during the week was organizational social organization and power and regime.Organizational construction is real beneficial to how things get done within an organization. By making sure that everyone has and role and knows what that role is then the organization can stay smoothly. This in turn has a huge effect on employee behavior. I think that organizational structure has a huge effect on the esprit de corps of the connection as well as the way employees argon treated and how they do their jobs. Lets say for example that the entering level employees at a company are doing all the spurt. They then turn that stoop into the managers who in turn submit it to the executive table. The board then gives praise to the managers and never acknowledges the employees who really did all the work.This can showcase low morale. Not only can this ca use low morale but it also overlooks and treats its entry level employees poorly. A way to set upon this would be organizational structure. When it is clear from the bottom up who does what in the company then those who do all the leg work get recognise for the hard work that they do. These employees no longer feel as if they are unimportant within the company and they do their jobs pause and at the kibosh of the day they are treated with the respect that they deserve and they per shape better at the job.Organizational Culture is the collecti ve behavior of people that are part of an organization and includes the meanings of their actions while being part of that organization. this includes the values, visions, norms, working language, systems, symbols, beliefs and habits. It has a large impact on behavior. It could either have a absolute impact or negative impact dependent on how the attractorship uses culture in a corporation. If the culture is applied equally to the differences of those in the company it could attend those of different backgrounds work with positive experiences.If a leader applies a cultural style that they adopted from another company it could work one of two ways. It could be effective and actually cause workers to work more effectively and with positive attitudes or it could bring down the general morale of the company in how they work together and how they can get together with the leadership styles. Overall behavior is dependent on the effectiveness of the performance of culture in the wor kplace. origin and Politics are necessary influences in to the high schoolest tier organizations today. Power is not a necessary evil and is most often contained within the position of authority. Politics is a little harder to describe. great deal often see it when an individual is attempting to influence a decision or position within an organization without a formal role or authority. In this paper I will analyze an organizational focus and leadership practices that impact organizations. I will also provide a couple real-world examples of the relationships between power and politics and how this relates to management and leadership practices.This week in chapter 13 we learned about the influence of power and politics on behavior in the work place. Power is the capacity to influence behavior in accordance to ones wishes. To have the capacity to control gentleman life you must control what they desire and ofcourse we know what that is, money. Its the scoop control method there is. If you dont listen you and your family will be starving on the street and you will lose your job. Seems homogeneous a pretty good control method to me. So basically chapter 13 confirms that money is power. Next it goes over the bases of power for example courtly Power is based on ones position in the actual organization. irresponsible Power which is the power destroy threaten inflict pain and nail peoples lives if the dont listen to you, its a great form of power, probably the crush. Reward Power which is the exact opposite Coercive Power because it is actually positive and rewards the employee instead of treating them as if they were a wage slave, its seldom used in our economy anymore but allow its still out there. Legitimate Power is in my best description just raw power. And Expert Power man if your an ripe and you got those special wizard skills your a real expert you have virtually expert power. So which bases of power are the most effective? booby hatch well it depends on the group of humans you have available to rein over and control, its all about personality. And that is why we like to bang into their minds and find out what makes them tick, whats important to them so we can use it as leverage etc. In the end it was a very good lesson and chapter about power and exerting it.Chapter 15 discusses the foundations of organization structure. Organizational structure is how jobs are formally divided or grouped. There are sixer elements that compose the organizational structure, work specialization, departmentalization, train of command, centralization and formalization. The three crude organizational objects are simple structure, which use a low degree of departmentalization, bureaucracy and matrix structure. A bureaucracy shows distinct characteristics such has part operating task, formalized rules, tasks are broken-up and grouped by specific departments, alter command and little control. Unlike the bureaucracy, the matrix structure uses two forms of departmentalization, the in operation(p) and the product. They use a dual chain of command and at times this type of command can lead to power struggles.Now-a-days new design options are available and decrease the amount of management that is found in the bureaucracy and the matrix structure. The virtual organization outsources many of the functions therefore one would find more centralization and less departmentalization.

The Micromanager

Although George substantiatems to be a nice man, he is in truth a true micromanager because he puke be persistent and stubborn on a exercise set of things. Although he would like to think that he is personable, at clear, he insists on getting things do in his deliver way and moderates track of Shelleys progress in doing it. He in any case eats up Shelleys meter in making her accompany him to meetings that take her concentration kayoed from true sue. blush at home, he stinker dictate the time his children need to do certain things like homework.George also insists that at least two press releases atomic number 18 published monthly even so when at that place is nonhing to write about. He oversteps on the instructions that Shelley has already devoted to her own staff which causes additional confusion on the part of their subordinates. Even if Shelley has already asked for assistance in the form of additional staff, he would soundless rather that she list down her priorities first and do things his way.Shelley obviously detests organism bullied into doing what should otherwise be something creative because she does not like Georges leaders style. However, leadership style can affect many people in different ways depending on personality types and the dapples they are in. This can be seen in the way Rich Harmon admires George for being innovative and ahead of him in thinking of solutions to his departments problems.The micromanager is good in doing everybody elses parley channel but as can be seen in Georges situation, he spends too practically time in dealing with the nitty gritty that should be delegated to his subordinates. As Chief-Executive-Officer, he should be concentrating on motivating his employees to do their work as a team up instead of finding the little pierce that they might be doing wrong or finding solutions to small problems that should be the job of his managers.2. Is it the appropriate style ? Why or why not? (Hint, consider the characteristics of the environment, the employee, the task, leader discretion, etc.)Retronics is in a very delicate situation because its market is going down and it needs to reinvent itself to keep up with the industry. Georges style cannot be successful in this send off because he insists on doing things hands-on while the need of the company is for its head to bring into being new ideas that could bring new life to the crippled corporation.George has his own following and he can be effective to certain types of personalities. However, although there are employees who admire Georges ideas that really help in the development of their departments, he is actually creating followers instead of true leaders because of the dependency destination he is encouraging. He should instead try to hone his managers leadership skills and assist more innovative ideas that come from below his rank if he really wants to keep up with the new wave in his industry. Otherwise, he would be trapped in solving everybody elses problems and no one impart be overseeing the company.On the other hand, his way of micromanaging Shelley causes her to loose motivation to work because she feels cramped by her position and his leadership style. It can be fake that Shelley might not be the only one who feels this way because he is the type who would really delve into the smallest of details of each department to keep him self abreast of what is happening within his company.Aside from embarrassing his managers for overmaster them in their own departments or divisions, Georges style can also cause a lot of confusion and power struggle which can be detrimental to a company who is already trying so hard to survive in an ailing industry. Instead of working towards a concrete goal, his style of management causes factions which can affect the time install and quality of work that needs to be done.Another negative return of Georges leadership style is that his managers will tend to imitate his leadership style and this could cause too much stress in the company. The tweet that is felt by the subordinates will just result to poor results delinquent to lack of morale. Instead of overseeing and managing, his executives would end up picking on their employees and atrophy too much time trying to correct mistakes that could have been done properly if they had the freedom to deal with things individually.Georges leadership style encourages identity instead of team building. A big company can suffer strong if its foundations are supportive groups of people instead of individuals who have their own motives for staying in the company. To be a good leader is to foster team work and intellectual among subordinates. Better relationships build loyalty and sincerity in getting things done.3. What strategies can Shelley employ to better manage her boss? (To adjudicate this question, you may want to read this short piece by arouse E. Chambers (You can find it through t he EBSCO database in Business reference work Complete).Shelley has to get over her judgments of being mislead into the predicament she was in. She has to stop feeling like a victim and put things in proper perspective. When emotions are put aside, she will be able to see that George is coming from a completely different background from hers. She is into the arts while George, an engineer academician standards, uses more of logic to understand and solve problems. She also has to go beyond her departments problems to understand that Georges problems are way much heavier than hers.Being a subordinate, it is also required of Shelley that she learns how to follow her boss even if it seems wrong. Otherwise, she can manipulate Georges decisions into her favor by finding out what motivates him to do things in another way. She can also use her communication skills in professionally sharing her ideas even before George can flutter it down. It can be seen that Shelley tends to just hold ba ck instead of verbally defending her ideas. Micromanagers can still feel in control as long as they see that their subordinates see their problems from the boss point of legal opinion too. Shelley should put her ideas to work and then find ways of explaining it to George in the light of his perception and not hers.Shelley also has to inform George of her ideas before she starts writing them. This way, they can discuss which ones he prefer and how they can compromise on how the report should be given treatment. Simply making a press release, for example, without pickings into consideration the boss view can be a ball up of time because of the corrections. However, if Shelley takes the initiative to place the information needed in search of her boss so that he just has to decide among the choices she offers, then things would be easier to do quickly.Shelley should also try to find out what makes George have a better relationship with the other managers. She does not have to suck u p to him and change her attitude but just analyzing those relationships could create better understanding of how to handle her boss.Lastly, Shelley really needs to go beyond her department and see things generally from the CEOs point of view too. Georges responsibilities are far harder to manage than hers and this could give her insight on why he treats her that way.

Although the two sides never fought against each other directly, the Cold War nonetheless erupted into frenzy at times in places like Vietnam, Korea, and Afghanistan. As the US grew more activist and interventionist in its foreign policy, the domestic government also grew in power and in its role in the peoples lives.WEEK 5 COMPLETE WORKHIS 204 Week 5 DQ 1 The Age of ReaganMost of us have lived much of our lives in the Age of Reagan, a period which dates from 1980 and which may still be ongoing now. Historians increasingly equalise that the election of Ronald Reagan in 1980 represented a revolution in American parliamentary law and, particularly, its p olitics. Review Reagans presidential career to explain what well-nigh it precisely was so revolutionary. Compare his approach to politics and foreign personal business with those of his predecessors, and assess the ways that his successors either built upon or attempted to turnaround his legacy. Explain why so many Americans opposed Reagans policies and those of his successors. press also the social and cultural changes which took place during the Age of Reagan. Finally, assess the success of the Reagan Revolution by identifying which problems it ameliorated and which it exacerbated. In your response, consider THREE of the following topics, with regard to how both Reagan and his successors handled or contributed to themHIS 204 Week 5 DQ 2 The Lived Experience of intermediate PeopleEspecially since the 1960s, historians have sought to understand history not just as a series of major(ip) events presided over by generals and statesmen, but also as the lived experience of ordinary p eople. For this last discussion, commence by reflecting on your own past with an eye toward how American society has changed over the course of your life. In your response, focus less on major political or international events than on the ways day-to-day life in America is different today from what it was when you were younger. You might consider such factors as the cost of goods and services, the forms of entertainment, means of communication, and so forth.HIS 204 Week 5 Final Paper Native American historyThesis statement Native American historyIntroductionIt has been seen that Native American history extents thousands of thousands of years and two continents. This is a versatilenarrative of full of life cultures that in turn generatedcomplicatedfinancialassociations and multifaceted political unions. In the course of it all, an association of First Peoples to the earth has stay behind a fundamentalsubject. Despite the fact that Native Americans of the areanowadaysrecognizedlike N ew England  assign identical languages and civilizations, recognizedlike Eastern Algonquian, we can say that they are not one political or societalcluster. To a certain extent, history comprises and still comprisesnumerous sub-groups. For instance, the Wampanoag reside in southeastern Massachusetts,the Pequots and Mohegans live in Connecticutat the same time as the Pocumtucks dwelt in the middle Connecticut River Valley close to todays Deerfield, Massachusetts (Bourne, 1990).

Organization and Culture Essay

Provide a brief ( bingle 1 paragraph) interpretation of the organization you chose to research. The fellowship that I chose to research is the company Google. Everyone is awargon of Google. It is the somewhat widely physical exertiond search engine in the world. Google is considered to be one of the best, if not the best search engine of solely fourth dimension. The company Google is considered to be a technological giant and a threat to other tech giants, for example Microsoft. Googles creators Larry knave and Sergey Binn, started this company in 1995. Google was first substantial to be a search engine, but it has crown to the point where it burn down be used as an internet browser also. Unlike its adversary Microsoft Internet Explorer, it has to be compatible with certain browsers in order to percentage at its fullest potential. Examine the culture of the selected organization.Googles integrated culture began with its forefathers philosophy, the famous 10 tenets. (Li sa Jackson 2013). And since Google is still controlled by its founders, that elbow room that the culture in part of the companys mantra. Googles founders Larry Page and Sergey Binn believe that trust is one of the most important aspects for the culture at Google. Google mission is a culture of choice. That is they argon not a stodgy company in the sense that they are not a break ones back to Wall Street, and that allows them to build a culture that leave behind deliver on this mission and that is principally organized to drive innovation. (Jeff Jarvis, 2013). Because of this trust that Google fosters to their employees, they are allowed to take risk, while being innovative. And with innovation comes feedback and collaboration. With this typewrite of corporate culture at Google, their employees are much much enthusiastic intimately the intellections that they present to the founders. There is not right or wrong carriage at Google, they are visionaries and as such can impleme nt and idea, and if it deeds, that fantastic, if the idea does not cause, then back to the drawing board.Again, it all stems from the trust ideas from the founders. Googles culture is very unique. At Google, they believe that if you focus on the user, all else will follow. They also believe that democracy on the web works and also that there is always more information out there. These are three out of the ten tenets that the founders of Google stand by. With these types of statements from one of the queen-sizedst technological companies, it is no wonder that Google is considered the number 1 place to work in the fall in States. Its because the founders allow the staff to develop ideas, make mistakes and they celebrate the misfortune instead of reprimanding or terminating the staff. This seemingly laid back culture fuels the imagination of the staff and gets them always looking for ways to improve not unspoiled the company, but themselves as well. Explain how you determine d that the selected organization showed the signs of the culture that you guard identified. When I pertinacious to do research on Google, and their culture, I decided to look at why this company is considered one of the best places to work in the United States. I asked myself, why is this company so customary? Why are their employees always happy? First you look at the culture. The founders believe in letting their employees be free to be innovative.They gather in a t-shirt and jeans work atmosphere, freedom to make mistakes and start everywhere again, etc. This is only part of the culture. Another aspect of the Google environment is ensuring that their employees are adequately compensated. Their benefits are also excellent. Googles employees enjoy free wellness and dental, free breakfast lunch and dinner. They also have an organic chef that caters to the unavoidably of the employees. Google found that women were leaving the company at twice the rate of everyone else. In spec ific, this occurred with new mothers. Googles maternity leave plan was 12 weeks remunerative time off. Human Resources changed the plan so new mothers could get 5 months paid time off with full pay and benefits. They were allowed to split this time up however they want. The result after the change in insurance policy? A 50% reduction in attrition for new mothers. Google tries to aim and retain the best employees. They do this based on data. When this data is collected, they use this information to gauge employees and improve their productivity.   correspond the factors that caused the organization to embody this particular culture.For Google, it seems as if the corporate culture that they have right now is doing and fine. Google was name the top place to work in 2012. But if for some modestness, they did decide to change their corporate culture, I reckon it would be to spread over to enhance on the 10 tenets that was there from conception. Of course as time, and conc epts changes over time, innovators such as Larry Page and Sergey Brinn will have to change as well.But, with a new CEO, Larry Page who is excited about leading the team into product development and technology strategy, but also keeping the stub of the company for what it was when they first started. Google is efficient and effective. caboodle magazine reported that Google does more business than their entire competitor combined, plus they do it at a lower cost. Because Google has a casual and democratic atmosphere, resulting in its distinction as a Flat company. The company does not boast a large middle management, and upper management is so hands on, its tough to qualify them in a separate category. Teams are made up of members with equal authority and a certain level of autonomy is maintained. Determine what type of leader would be best suited for this organization. Support your position. The type of leader that would be best suited for Google is a Transformational Leader. Transformational leadership is a type of leadership style that can urge positive changes in those who follow. Transformational leaders are generally energetic, enthusiastic, and passionate. Not only are these leaders concerned and involved in the process they are also centre on helping every member of the group succeed as well. Through the strength of their vision and personality, transformational leaders are able to inspire followers to change expectations, perceptions, and motivations to work towards common goals. They have the ability to tuck trust, respect and admiration from their followers. Imagine that there is a decline in the demand of products or services supplied by the selected organization. Determine what the change in culture would need to be in response to this situation. If for some reason there is a decline for the products and services supplied by Google, I think that the founders will continue to have the same culture that they originally started the compan y with. And I say that because, so far that culture seems to be what has Google as one of the top tech giants in the world. Of course, the founders Larry Page and Sergey Binn, being the visionaries that they are, as times and concepts changes over time, they will have to change as well. They will always have to be one step ahead of the competition, if think to last in the technological game.ReferencesThe Real Secret of Googles collective Culture by Lisa Jackson, July 2013. https//www.web-ebschohost-com.libdata.strayer.edu/ehost/deliveryArticle Refreshing Google.

Bilingualism in Children

Bilingualism tr axerophthol be viewed in twain several(predicate) ways. One way of exhibit bilingualism is that it is a commendable trait for a person to charter, that is alongside the thinking that it is a do of high intellect. Another way of viewing bilingualism is that it is a negative upshot of Globalism, that it is a degradation of culture. It is undeniable that bilingualism is a preponderant topic in todays society. Some even consider it as an essential trait for survival in the context of the modern world.This notion of bilingualism is peculiarly prevalent in the US, where immigrants should adopt a sanction vocabulary to be war-ridden in terms of employment. That is why babyren from immigrant families atomic number 18 advised by their p arents to learn a second expression primal as early as possible. The problem bilingualism arises when parents split to consider that sm entirely fryren are still in the stage of mastering their first linguistic communication . getting two linguistic communication simultaneously is would be difficult for anyone regardless of age. It is a universal notion that the children would eventually learn the second language.That is alongside the thinking that, as the children are exposed more to the society m placeh the second language, the children would naturally the language. Although, it is observable that children from immigrant families bit by bit become more and more favourable with second language with time. exactly it is also observable that the process that the children have to go through is not an favourable one. The difficulty of childrens erudition of a second language is expressed by Eva Hoffman in her hold in Lost in Translation. She had thrown in a actually helpful query for this discussion how does an several(prenominal) bend toward another culture without stumbling all over? (Hoffman 209) Hoffmans semi-autobiographical book is rough her make do to undertake a second language w hen family had migrated from Poland to Vancouver. The bulk of the book is about her doomed of her sense of place and belonging in her new society. But the fact that the acquisition of the second language would come as natural would not necessarily correspond that the children would not be subjected to the consequences of organism bilingual.Another book that would be helpful to the discussion at hand is Natasha Lvovichs The Multilingual ego An inquiry to language learning. In ancestry to Hoffmans subject area, Lvovichs book had taken a more attention-grabbing approach. Lvovichs work is about the struggles that her female child had to face when they had go to America. Although there are some mild differences between the two books, they are twain talking the afore oralise(prenominal) topic of language acquisition. Both of the books had depicted how a child is subjected to consequences of existence bilingual.A vernacular consequence of bilingualism as Lvovich had depicted through the story of her young lady she is going through a actually difficult period of adjustment as a teenager growing into due date (Lvovich 101) There was even a blame in the book that Lvovichs daughter became reluctant to speak their first language. Hoffman argued that a reluctance to speak the first language would result to the atrophy of the mother language of the child (Hoffman 98) ConclusionFor children of immigrant families to succeed in being multilingual, their parents should first do careful proviso and learning about the nature of language acquisition. The parents should always keep in soul that childhood is already full of challenges as is. They should be aware of the consequence of being bilingual and they should also have at least an idea of how to counter them. deeds Cited Hoffman, Eva. (1990). Lost in Translation A Life in a youthful Language. NY Penguin Lvovich, N. (1997). The Multilingual Self An inquiry into language learning. Mahwah, NJ Lawrence Erlba um AssociatesBilingualism in ChildrenBilingualism is the production and/or comprehension of two languages by the same individual (Cummins, 1981). Many children of varying nationality, acquire this ability of learning two languages through cultural maintenance and educational enrichment. Furthermore, the media incessantly bombards children of stimulation of the other language (Cummins, 1981). Cummins (1981) give tongue to that there is a strong inclining among children of replacing the first language with the other. A series of tests were made by Feldman and Shen (1969) about some language- colligate cognitive receiptss of bilingual cinque year olds.Three tasks for children were made accordingly to gather information. These tasks of increasing difficulty were (1) butt constancy, (2) appointee and (3) victimization labels in sentences, respectively . In object constancy, children were primarily staten with objects such as cups, plates, sponge, spouse and suction cup max hol der. These objects were later physically transformed in front of them. Crushing the cups, burning the match and painting the plates were some ex adenylic acidles of transformation. Transformed objects are placed beside an identical pre-transformed objects.Afterwards, the children were asked to identify which among the two was primarily shown. Naming, on the other hand, by choice tests the childs ability to use verbal labels to stimulate familiar objects. The experimenter tried to confuse the children by switching the call of the familiar object and designating nonsensical name to objects. For ex amperele, calling an planer as car and relabeling the cup as wug. The children were asked which among the objects was really an airplane. They were also asked which one was called a wug and then they were asked what it really was.In the third experiment, the child was requested to show his ability of exploitation three sorts of labels in simple relational sentences such as The cup is on the plate. These labels, as discussed in naming, were common names, switched common names and nonsense names. The principle for using simple relational sentences was that referential watchword meaning is the simplest sort of meaning. Words alike cup, plate and even the take leave of the predicate on can all be thought of as referring to things. Results showed that bilinguals accomplish significantly better in the said three tasks than monolinguals do (Feldman & Shen, 1969).Moreover, bilinguals advantage over monolinguals was more apparent in comprehension than production measures. These means they hunt down better where nonverbal pointing responses were required. In addition, functions related to labeling would be more advanced by having two languages. Research by Bialystok (2004), on the other hand, has shown that bilingual children develop promise processes more readily than monolinguals do. They respond more rapidly to conditions that placed greater demands on workin g memory and carry out controlled processes more effectively (Bialystok, 2004).On the other hand, Macnamara (1966) argued some studies have reported negative effects of bilingualism (as cited in Bialystok, 2004). In Feldman & Shens (1969) experiment, it was build out that monolinguals do better in the use of either common names alone or nonsense names alone. Furthermore, Fishman (1967) added that disadvantages commonly associated with bilingualism would not appear in bilinguals whose languages were situation specific (as cited in Feldman & Shen, 1969). It was an accepted notion that bilinguals had deficits compared with monolingual peers.Nonetheless, studies show significant cognitive advantages of children with bilingual capacities. These advantages were possessive in comprehending rather than performing verbal actions. Other research pointed out bilingual advantages in the areas of creativity, problem solving and perceptual disembedding (Bialystok, 2004). These advantages of bilinguals can be uniquely attributed to an early development in association and labeling skills (Feldman & Shen, 1969). Bibliography Bialystok, E. , Craik, F. I.

(Appendix B) Mail Reflectors The way intimately(prenominal) people keep up to date on network news is through subscription to a government issue of mail reflecting telescopes.Mail reflectors are special electronic mailboxes which, when they receive a inwardness, resend it to a disputation of other mailboxes. This in effect creates a discussion group on a dampenicular topic. Each subscriber sees all the mail precedented by the reflector, and if one wants to put his two cents in sends a nub with the commen ts to the reflector. The general format to subscribe to a mail cite is to find the address reflector and append the string -REQUEST to the mailbox name (not the host name). For physical exercise, if you wanted to take part in the mailing list for NSFnet reflected by email&160protectedNSF. NET, one sends a request to Get any book for free on www. Abika. com The Hitchhikers Guide to the Internet email&160protected NSF. NET. This may be a wondrous scheme, but the problem is that you must contend the list exists in the first place. It is suggested that, if you are preceding(a)imeed, you read the mail from one list (like NSFNET) and you will probably become familiar with the existence of others. A registration service for mail reflectors is provided by the NIC in the blames NETINFOINTEREST-GROUPS-1. TXT, NETINFOINTEREST-GROUPS-2. TXT, and NETINFOINTEREST-GROUPS3.TXT. The NSFNET mail reflector is targeted at those people who have a day to day interest in the news of the NSFnet (the endorsebone, regional network, and Internet inter- association site workers). The meanss are reflected by a central location and are move as separate messages to severally subscriber. This creates hundreds of messages on the wide sphere of influence networks where bandwidth is the scarcest. on that point are two ways in which a campus could spread the news and not cause these messages to inundate the wide landing field networks. unmatchable is to re-reflect the message on the campus.That is, set up a reflector on a local car which forwards the message to a campus diffusion list. The other is to create an alias on a campus car which places the messages into a stigmatises burden on the topic. Campus users who want the information could access the notesfile and see the messages that have been direct since their last access. angiotensin converting enzyme aptitude in addition elect to have the campus wide area network liaison screen the messages in either case and preci sely forward those which are dish outed of merit. Either of these schemes allows one message to be sent to the campus, while allowing wide distribution in spite of appearance. Address Allocation sooner a local network can be connected to the Internet it must be allocated a unique IP address. These addresses are allocated by ISI. The allocation process consists of getting an application form received from ISI. (Send a message to email&160protected arpa and ask for the usher for a connected address). This template is filled out and mailed back to hostmaster. An address is allocated and e-mailed back to you. This can likewise be through with(p) by postal mail (Appendix B). IP addresses are 32 bits long. It is usually written as quaternity decimal numbers degage by periods (e. . , 192. 17. 5. 100). Each number is the value of an eighter of the 32 bits. It was seen from the head start that some networks might subscribe to organize themselves as genuinely flat (one net with a survey of pommels) and some might organize hierarchically -6(many interconnected nets with fewer nodes for each one and a backbone). Get any book for free on www. Abika. com The Hitchhikers Guide to the Internet To provide for these cases, addresses were dissimilariated into correct A, B, and C networks. This potpourri had to with the interpretation of the ogdoads. menage A networks have the first octet as a network address and the remaining deuce-ace as a host address on that network. mark C addresses have three octets of network address and one of host. Class B is break up two and two. thitherfore, at that place is an address space for a few large nets, a reasonable number of medium nets and a large number of small(a) nets. The top two bits in the first octet are coded to tell the address format. All of the class A nets have been allocated. So one has to choose betwixt Class B and Class C when placing an order. (There are similarly class D (Multicast) and E (Experimen tal) formats.Multicast addresses will apparent come into greater use in the near approaching, but are not frequently apply now). In the past sites requiring s unconstipated-f ancient network addresses requested octuple discrete addresses (usually Class C). This was done because much of the software available (not ably 4. 2BSD) could not deal with subnetted addresses. Information on how to stretchability a concomitant network (routing information) must be enclosed in Internet gates and bundle switches. Some of these nodes have a hold in capability to store and exchange routing information (limited to about 300 networks).Therefore, it is suggested that any campus state (make known to the Internet) no much than two discrete network numbers. If a campus expects to be constrained by this, it should con side of meatr subnetting. Subnetting (RFC-932) allows one to announce one address to the Internet and use a set of addresses on the campus. Basically, one situates a bury wh ich allows the network to distinguishableiate between the network mess and host portion of the address. By using a different mask on the Internet and the campus, the address can be interpreted in quintuple ways.For example, if a campus requires two networks internally and has the 32,000 addresses beginning 128. 174. X. X (a Class B address) allocated to it, the campus could allocate 128. 174. 5. X to one part of campus and 128. 174. 10. X to another. By advertising 128. 174 to the Internet with a subnet mask of FF. FF. 00. 00, the Internet would treat these two addresses as one. Within the campus a mask of FF. FF. FF. 00 would be utilise, allowing the campus to treat the addresses as separate entities. (In verity you dont pass the subnet mask of FF. FF. 00. 0 to the Internet, the octet meaning is implicit in its universe a class B address). A word of warning is necessary. Not all systems know how to do subnetting.

Some motorcars used an address of all zeros to mean political program and some all ones. This was confusing when railcars of both type were connected to the same network. The broadcast address of all ones has been adopted to end the grief. Some systems (e. g. 4. 2 BSD) allow one to choose the format of the broadcast address. If a system does allow this choice, care should be taken that the all ones format is chosen. (This i s explained in RFC-1009 and RFC-1010). 8Internet Problems There are a number of problems with the Internet. Solutions to the problems range from software changes to long term research projects. Some of the major ones are detailed below Number of Networks When the Internet was designed it was to have about 50 connected networks. With the explosion of networking, the number is now approaching 300. The software in a group of critical portals (called the core gateways of the ARPAnet) are not able to pass or store much more than that number. In the shortsighted term, core reallocation and recode has raised the number slightly.By the summer of 88 the current PDP-11 core gateways will be replaced with BBN dawdle gateways which will cream the problem. Routing Issues Along with mere mass of the data necessary to dispatch sells to a large number of networks, there are many problems with the updating, stability, and optimumity of the routing algorithmic programs. Much research is cre ation done in the area, but the optimal solution to these routing problems is still eld away. In most cases the the routing we have forthwith works, but sub-optimally and some time unpredictably. -8-Trust Issues doors exchange network routing information. Currently, most gateways accept on trustingness that the information provided about the state of the network is correct. In the past this was not a big problem since most of the gateways belonged to a single administrative entity (DARPA). Now with triune wide area networks under different administrations, a imp gateway someplace in the net could cripple the Internet. There is design work going on to solve both the problem of Get any book for free on www.

Capacity &038 over-crowding Many portions of the ARPAnet are very con gested during the busy part of the day. Additional relate are be after to alleviate this congestion, but the implementation will take a few months. 9 These problems and the future direction of the Internet are pertinacious by the Internet intriguer (Dave Clark of MIT) being advised by the Internet Activities Board (IAB).This board is composed of chairmen of a number of committees with responsibility for various specialized areas of the Internet.

To appreciate the problem, watch a small child trying to find a flurry in a restaurant. From the adult point of adopt the structure of the eat room is seen and an optimal passageway easily chosen.The child, however, is presented with a set of roadways between tables where a good government agency, let alone the optimal one to the goal is not discernible. *** A little more background might be appropriate. IP gateways (more correctly routers) are boxes which have connections to multiple networks and pass business between these nets. They decide how the packet is to be sent based on the information in the IP header of the packet and the state of the network. Get any book for free on www. Abika. com The Hitchhikers Guide to the Internet Each interface on a router has an unique address appropriate to the network to which it is connected.The information in the IP header which is used is primarily the destination address. otherwise information (e. g. type of service) is largely ignored at this time. The state of the network is determined by the routers transient information among themselves. The distribution of the database (what each node knows), the form of the updates, and rhythmic pattern used to measure the value of a connection, are the parameters which determine the characteristics of a routing communications protocol. under(a) some algorithms each node in the network has complete knowledge of the state of the network (the adult algorithm).This implies the nodes must have big amounts of local storage and enough CPU to search the large tables in a short enough time (remember this must be done for each packet). Also, routing updates usually c ontain notwithstanding changes to the brisk information (or you spend a large amount of the network capacity dismission around megabyte routing updates). This type of algorithm has several problems. Since the scarcely way the routing information can be passed around is crossways the network and the propagation time is non-trivial, the view of the network at each node is a correct historical view of the network at varying times in the past. The adult algorithm, but quite an than looking directly at the dine area, looking at a picture show of the dining room. angiotensin converting enzyme is in all probability to survival of the fittest the optimal route and find a bus-cart has moved in to block the path after the photo was taken). These inconsistencies can cause circular routes (called routing loops) where once a packet enters it is routed in a closed path until its time to live (TTL) field expires and it is discarded. Other algorithms may know about only a subset of the ne twork. To celebrate loops in these protocols, they are usually used in a hierarchical network.They know completely about their own area, but to leave that area they go to one particular place (the neglectfulness gateway). Typically these are used in smaller networks (campus, regional ). -10Routing protocols in current use Static (no protocol-table/default routing) Dont laugh. It is probably the most reliable, easiest to implement, and least likely to get one into trouble for a small network or a leaf on the Internet. This is, also, the only rule available on some CPU-operating system combinations.If a host is connected to an Ethernet which has only one gateway off of it, one should make that the default gateway for the host and do no other routing. (Of course that gateway may pass the reachablity information somehow on the other side of itself). One word of warning, it is only with fundamental caution that one should use unruffled routes in the centre of attention of a networ k 10 Get any book for free on www. Abika. com The Hitchhikers Guide to the Internet which is also using high-powered routing. The routers passing dynamic information are sometimes confused by conflicting dynamic and atmospheric stable routes.If your host is on an ethernet with multiple routers to other networks on it and the routers are doing dynamic routing among themselves, it is usually get around to take part in the dynamic routing than to use static routes. 11 perpetrate pluck is a routing protocol based on XNS (Xerox Network System) adapted for IP networks. It is used by many routers (Proteon, cisco, UB ) and many BSD Unix systems BSD systems typically run a program called routed to exchange information with other systems running teardrop. commit works outmatch for nets of small diameter where the connectors are of equal speed.The reason for this is that the metric function used to determine which path is outgo is the hop-count. A hop is a traverse crosswise a gat eway. So, all machines on the same Ethernet are zero record hop away. If a router connects connects two networks directly, a machine on the other side of the router is one hop away. As the routing information is passed through a gateway, the gateway adds one to the hop counts to keep them consistent crosswise the network. The diameter of a network is delimitate as the largest hop-count possible at heart a network. Unfortunately, a hop count of 16 is de attractived as infinity in pedigree meaning the tie in is down.Therefore, prodigal will not allow hosts separated by more than 15 gateways in the RIP space to communicate. The other problem with hop-count metrics is that if links have different speeds, that difference is not -11reflected in the hop-count. So a one hop planet link (with a . 5 sec persist) at 56kb would be used alternatively of a two hop T1 connection. Congestion can be viewed as a decrease in the efficacy of a link. So, as a link gets more congested, RIP will sti ll know it is the dress hat hop-count route and congest it even more by throwing more packets on the queue for that link.The protocol is not well(p) documented. A group of people are working on producing an RFC to both define the current RIP and to do some extensions to it to allow it to intermit cope with larger networks. Currently, the best documentation for RIP appears to be the code to BSD routed. Routed The ROUTED program, which does RIP for 4. 2BSD systems, Get any book for free on www. Abika. com The Hitchhikers Guide to the Internet has many elections. One of the most frequently used is routed -q (quiet mode) which means find out to RIP information but never broadcast it.This would be used by a machine on a network with multiple RIP verbalize gateways. It allows the host to determine which gateway is best (hopwise) to use to reach a removed(p) network. (Of course you might want to have a default gateway to prevent having to pass all the addresses known to the Interne t around with RIP). There are two ways to insert static routes into routed, the /etc/gateways file and the route add command. Static routes are useful if you know how to reach a distant network, but you are not receiving that route using RIP. For the most part the route add command is pet to use.The reason for this is that the command adds the route to that machines routing table but does not export it through RIP. The /etc/gateways file takes precedence over any routing information received through a RIP update. It is also broadcast as fact in RIP updates produced by the host without question, so if a sneak is made in the /etc/gateways file, that mistake will soon permeate the RIP space and may bring the network to its knees. One of the problems with routed is that you have very little ensure over what gets broadcast and what doesnt.Many times in larger networks where various parts of the network are under different administrative controls, you would like to pass on through RIP only nets which you receive from RIP and you know are reasonable. This prevents people from adding IP addresses to the network which may be black-market and you being responsible for passing them on to the Internet. This -12type of reasonability checks are not available with routed and leave it usable, but inadequate for large networks. 12 Hello (RFC-891) Hello is a routing protocol which was designed and implemented in a experimental software router called a Fuzzball hich runs on a PDP-11. It does not have wide usage, but is the routing protocol currently used on the NSFnet backbone. The data transferred between nodes is similar to RIP (a list of networks and their metrics). The metric, however, is milliseconds of block. This allows Hello to be used over nets of various link speeds and practices better in congestive situations. One of the most interesting side personal effects of Hello based networks is their great timekeeping ability. If you consider the problem of mensuration jibe on a link for the metric, you find that it is not an easy thing toGet any book for free on www. Abika. com The Hitchhikers Guide to the Internet do. You cannot measure round trip time since the return link may be more congested, of a different speed, or even not there. It is not rattling feasible for each node on the network to have a builtin WWV (nationwide piano tuner time standard) receiver. So, you must design an algorithm to pass around time between nodes over the network links where the delay in transmission can only be approximated. Hello routers do this and in a nationwide network maintain synchronized time within milliseconds. 13Exterior Gateway Protocol (EGP RFC-904) EGP is not strictly a routing protocol, it is a reachability protocol. It tells only if nets can be reached through a particular gateway, not how good the connection is. It is the standard by which gateways to local nets inform the ARPAnet of the nets they can reach. There is a metric passed around by EGP but its usage is not standardized formally. Its typical value is value is 1 to 8 which are arbitrary virtuousness of link values understood by the internal DDN gateways. The smaller the value the better and a value of 8 being unreached.A quirk of the protocol prevents distinguishing between 1 and 2, 3 and 4 , so the usablity of this as a metric is as three values and unaccessible. Within NSFnet the values used are 1, 3, and unaccessible. Many routers talk EGP so they can be used for ARPAnet gateways. -13Gated So we have regional and campus networks talking RIP among themselves, the NSFnet backbone talking Hello, and the DDN speaking EGP. How do they interoperate? In the beginning there was static routing, assembled into the Fuzzball software configured for each site.The problem with doing static routing in the middle of the network is that it is broadcast to the Internet whether it is usable or not. Therefore, if a net becomes unreachable and you try to get there, dynamic rou ting will nowadays issue a net unreachable to you. Under static routing the routers would think the net could be reached and would continue trying until the application gave up (in 2 or more minutes). Mark Fedor of Cornell (email&160protected tn. cornell. edu) attempted to solve these problems with a replacement for routed called gated. Gated talks RIP to RIP speaking hosts, EGP to EGP speakers, and Hello to Helloers.These speakers frequently all live on one Ethernet, but luckily (or unluckily) cannot understand each others ruminations. In addition, under configuration file control it can filter the conversion. For example, one can produce a Get any book for free on www. Abika. com The Hitchhikers Guide to the Internet configuration formula announce RIP nets via Hello only if they are specified in a list and are reachable by way of a RIP broadcast as well. This means that if a rogue network appears in your local sites RIP space, it wont be passed through to the Hello side of the w orld.There are also configuration options to do static routing and name trusted gateways. This may sound like the greatest thing since sliced bread, but there is a catch called metric conversion. You have RIP measuring in hops, Hello measuring in milliseconds, and EGP using arbitrary small numbers. The big questions is how many hops to a millisecond, how many milliseconds in the EGP number 3. Also, remember that infinity (unreachability) is 16 to RIP, 30000 or so to Hello, and 8 to the DDN with EGP. Getting all these metrics to work well together is no small feat.If done wrongly and you translate an RIP of 16 into an EGP of 6, everyone in the ARPAnet will still think your gateway can reach the unreachable and will send every packet in the world your way. For these reasons, Mark requests that you consult intimately with him when configuring and using gated. -14&8243 name calling All routing crosswise the network is done by means of the IP address associated with a packet. Since do main find it difficult to remember addresses like 128. 174. 5. 50, a symbolic name take was set up at the NIC where people would say I would like my host to be named uiucuxc.Machines connected to the Internet across the nation would connect to the NIC in the middle of the night, check modification dates on the hosts file, and if modified move it to their local machine. With the advent of workstations and micros, changes to the host file would have to be made nightly. It would also be very bray intensive and consume a wad of network bandwidth. RFC-882 and a number of others set forth domain name service, a distributed data base system for mapping label into addresses. We must look a little more closely into whats in a name. First, note that an address specifies a particular connection on a specific network.If the machine moves, the address changes. Second, a machine can have one or more name calling and one or more network addresses (connections) to different networks. Names po int to a something which does useful work (i. e. the machine) and IP addresses point to an interface on that provider. A name is a rigorously symbolic representation of a list of addresses on the network. If a machine moves to a different network, the addresses will change but the name could remain the same. solid ground names are tree structured names with the root of the tree at the right. For example 14 Get any book for free on www. Abika. om The Hitchhikers Guide to the Internet 15 uxc. cso. uiuc. edu is a machine called uxc (purely arbitrary), within the subdomains method of allocation of the U of I) and uiuc (the University of Illinois at Urbana), registered with edu (the set of educational institutions). A alter model of how a name is single-minded is that on the users machine there is a resolver. The resolver knows how to contact across the network a root name horde. Root servers are the base of the tree structured data retrieval system. They know who is responsible for treatment first level domains (e. g. edu).What root servers to use is an installation parameter. From the root server the resolver finds out who provides edu service. It contacts the edu name server which supplies it with a list of addresses of servers for the subdomains (like uiuc). This action is repeated with the subdomain servers until the final subdomain returns a list of addresses of interfaces on the host in question. The users machine hence has its choice of which of these addresses to use for communication. -15A group may apply for its own domain name (like uiuc above). This is done in a manner similar to the IP address allocation.The only requirements are that the requestor have two machines reachable from the Internet, which will act as name servers for that domain. Those servers could also act as servers for subdomains or other servers could be designated as such. Note that the servers need not be located in any particular place, as long as they are reachable for name r esolution. (U of I could ask Michigan State to act on its behalf and that would be fine). The biggest problem is that soulfulness must do maintenance on the database. If the machine is not convenient, that might not be done in a timely fashion.The other thing to note is that once the domain is allocated to an administrative entity, that entity can freely allocate subdomains using what ever manner it sees fit. The Berkeley Internet Name sphere ( truss) Server implements the Internet name server for UNIX systems. The name server is a distributed data base system that allows clients to name resources and to share that information with other network hosts. stand by is integrated with 4. 3BSD and is used to lookup and store host names, addresses, mail agents, host information, and more. It replaces the /etc/hosts file for host name lookup. go for is still an evolving program.

BIND can also be obtained via anonymous FTP from ucbarpa. berkley. edu. There are several advantages in using BIND. One of the most burning(prenominal) is that it frees a host from relying on /etc/hosts Get any book for free on www. Abika. com The Hitchhikers Guide to the Internet being up to date and complete. Within the . uiuc. edu domain, only a few hosts are included in the host table distributed by SRI.The balance wheel are listed locally within the BIND tables on uxc. cso. uiuc. edu (the server machine for most of the . uiuc. edu domain). All are equally reachable from any other Internet host running BIND. BIND can also provide mail forwarding information for interior hosts not directly reachable from the Internet. These hosts can either be on non-advertised networks, or not connected to a network at all, as in the case of UUCP-reachable hosts. More information on BIND is available in the Name Server Operations Guide for B IND in UNIX System Managers Manual, 4. 3BSD release.There are a few special domains on the network, like SRINIC. ARPA. The arpa domain is historical, referring to hosts registered in the old hosts database at the NIC. There are others of the form NNSC. NSF. NET. These special domains are used slenderly and require ample justification. They refer to servers under the administrative control of -16the network sort of than any single organization. This allows for the actual server to be moved around the net while the user interface to that machine remains constant. That is, should BBN relinquish control of the NNSC, the new provider would be pointed to by that name.In actuality, the domain system is a much more general and complex system than has been described. Resolvers and some servers cache information to allow steps in the resolution to be skipped. Information provided by the servers can be arbitrary, not merely IP addresses. This allows the system to be used both by non-IP netwo rks and for mail, where it may be necessary to give information on intermediate mail bridges. 16 Whats wrong with Berkeley Unix University of California at Berkeley has been funded by DARPA to modify the Unix system in a number of ways.Included in these modifications is support for the Internet protocols. In earlier versions (e. g. BSD 4. 2) there was good support for the basic Internet protocols (transmission control protocol, IP, SMTP, ARP) which allowed it to perform nicely on IP ethernets and smaller Internets. There were deficiencies, however, when it was connected to complicated networks. almost of these problems have been resolved under the newest release (BSD 4. 3). Since it is the springboard from which many vendors have launched Unix implementations (either by porting the existing code or by using it as a model), many implementations (e. g.Ultrix) are still based on BSD 4. 2. Therefore, many implementations still exist with the BSD 4. 2 problems. As time goes on, when BSD 4. 3 trickles through Get any book for free on www. Abika. com The Hitchhikers Guide to the Internet vendors as new release, many of the problems will be resolved. Following is a list of some problem scenarios and their handling under each of these releases. ICMP sends Under the Internet model, all a system needs to know to get anywhere in the Internet is its own address, the address of where it wants to go, and how to reach a gateway which knows about the Internet.It doesnt have to be the best gateway. If the system is on a network with multiple gateways, and a host sends a packet for delivery to a gateway which feels another directly connected gateway is more appropriate, the gateway sends the sender a message. This message is an ICMP redirect, which politely says Ill deliver this message for you, but you really ought to use that gateway over there to reach this host. BSD 4. 2 ignores these messages. This creates more stress on the gateways and the local network, since for every packet -17sent, the gateway sends a packet to the originator.BSD 4. 3 uses the redirect to update its routing tables, will use the route until it times out, thus revert to the use of the route it thinks is should use. The whole process then repeats, but it is far better than one per packet. Trailers An application (like FTP) sends a string of octets to TCP which breaks it into chunks, and adds a TCP header. TCP then sends blocks of data to IP which adds its own headers and ships the packets over the network. All this prepending of the data with headers causes store moves in both the sending and the receiving machines.Someone got the bright idea that if packets were long and they stuck the headers on the end (they became monotones), the receiving machine could put the packet on the beginning of a page boundary and if the trailer was OK merely delete it and transfer control of the page with no memory moves involved. The problem is that trailers were never standardized and most ga teways dont know to look for the routing information at the end of the block. When trailers are used, the machine typically works fine on the local network (no gateways involved) and for short blocks through gateways (on which trailers arent used).So TELNET and FTPs of very short files work just fine and FTPs of long files seem to hang. On BSD 4. 2 trailers are a boot option and one should make sure they are off when using the Internet. BSD 4. 3 negotiates trailers, so it uses them on its local net and doesnt use them when going across the network. 17 Get any book for free on www. Abika. com The Hitchhikers Guide to the Internet Retransmissions TCP fires off blocks to its partner at the far end of the connection. If it doesnt receive an acknowledgement in a reasonable amount of time it retransmits the blocks.The finding of what is reasonable is done by TCPs retransmission algorithm. There is no correct algorithm but some are better than others, where better is measured by the numbe r of retransmissions done unnecessarily. BSD 4. 2 had a retransmission algorithm which retransmitted promptly and often. This is exactly what you would want if you had a caboodle of machines on an ethernet (a low delay network of large bandwidth). If you have a network of relatively longer delay and scarce bandwidth (e. g. 56kb lines), it tends to retransmit too aggressively.Therefore, it makes the networks and gateways pass more traffic than is really necessary for a given conversation. Retransmission algorithms do adapt to the delay of the network -18after a few packets, but 4. 2s adapts slowly in delay situations. BSD 4. 3 does a lot better and tries to do the best for both worlds. It fires off a few retransmissions really quickly anticipate it is on a low delay network, and then backs off very quickly. It also allows the delay to be about 4 minutes before it gives up and declares the connection broken. -19Appendix A References to Remedial Information 18Quaterman and Hoskins, illustrious Computer Networks, Communications of the ACM, Vol 29, 10, pp. 932-971 (October, 1986).
